' Tirellwhom wmg/jconccm." M BeA it known `that 1 BERNARD MiiLLs, a citizen oi:lv` the United States, residingat Brooklyn, inthe county of Kings andl State 5 of,l New York, have inventedV certain new andj useful Improvements in Heating Systems, oiwvhichtheAtollo-Wing is a full, clear, andexact' description'.

rlhis VinventionV relates to the heating of congea-led" or thickened liquids to render them liquid or mobile and' to maintain tl'iem in., that, condition. .Many substances, such; its, for. example, heavy` petroleum oils, asphalt,4 molasses, etc., congealj or thicken 1| into a solid. or z(jrelatinous massbelow certain temperatures and when. iny that condition their removal .andi transferA presents. manyy ditticult-ies,yV lvhile theapplication of sufficient heat will ijeildij them mobile and easily handledf by pipes,` diinculty has here- OfOl'eYbeeneiqgerieneedj in applyingr` thefheat successfully... common method hereto-l fore. employed. fOlL applyingv the heat has been by means ot steam coils locatedlpwithln '25 the storageA tanks. With this method the 11i-ass,immediately surrounding, the coils will berendered. mobile or, liquid, but asnosuccessful' circulating.' means` has YbeenH'pprovidedthe.remainder oi the mass Willfbe sub,- stantially unaffected. A If there is a leak in the coils the substance being handledjis di'- l'uted, auch thewater soadded must besub` sequently removed, In orderto make re-. pairs oii'toestablish theexistence'of a leak, the tank must first, be` emptied. The .steam coils also occupy considerable space and, den

crease the capacityfof the tanks. In marine installationsfthe space betweenfthe inner and outer bottom skins of a shipV is. com. monly utilized for tanks. for the storage of. the heavy fuel. oil and. because of the proximity of die tanks to the cold sea Water, the oil quickly congea-ls or solidifies,

'lhesetanksare very inaccessible because. ofL

ship, and caving. to-l the. large yamount oi bracing in. these` tanks. .the installation o their location inl the extreme: bot-tomen the" object is to provideY a system in which the piping necessary Withinatank is very small with' aconseque'nt elimination ofv danger of leaky joints, in which the piping` is` practic-ally all exposed'andireadily accessible for inspectionand repair., and in-Which thecapacity of. the tanks isy not materially 'decreased,V A further object is to providea system which isfcomparatively inexpensive and simple-in construction, installation and operation, which isreli'able, rapidy and ef# 'cie'n-t, which permits of a positive control oflthetemperature of the contents of a storageA tank, and in which repairs can bey eflfe'cted Without first removing the contents oi' any-off` the tanks. Other objects andv advantages Will be apparent from"A the followingmdescription and the novelE features ofy my invention Will'f be particularly pointed out `in Claims. A k'lhe invention contemplates the preliminary heating ofr a quant-ity of a liquid, preferably Qf the same substancev as that in the s, storage tank, transferring this .liquid lpreif'e'rably as a jet into 'direct contact with the thickened, congealed, or jellied sub-v stance to break upand dissolve or liquefy a portion of the same and absorb it into the treating. liquid, removing the mixture,.heat ingpit, and reapplying it tostored. substance, repeatedly until-'theentire content of a tank is inade liquid andv mobile. and raised toa desired temperature, Al portion ofthe circulating mixture can be'v diverted to.. another or intermediate tank, or utilized in any desiredjmanner at the same time that the'conjy tents of a tank are being' liquefied or'maintained" in a liquid condition. The invention also comprises certain details arrangements which Will be more fully hereinafter described. y 11.1. the. wompanyns drawing. the ligure iS a.
